Digital sovereignty is being called for by the European Commission, the German government and the state government of Hesse. This objective has met with a great deal of approval in the political debate. On the one hand, this is because the dependence on hardware and software from the USA and China and on services from global IT corporations means that there is a great need for self-determination in the use of information technology. Another reason is that the concept of digital sovereignty is not very clear-cut. It therefore makes sense to define more precisely what is to be understood by digital sovereignty from the perspective of data protection and IT security. Only then can it be determined to what extent digital sovereignty is possible, with what strategies and by what means it can be pursued, and whether the disadvantages that arise in the process should be accepted. The event will explore these questions from the perspectives of data protection and IT security.
